Tungsten heavy alloys (the density is 16.0-18.5g/cm3) are made of tungsten based two phase composites with Ni, Fe or Cu as additions to form a ductile matrix. Tungsten Heavy Alloy has good machining properties, excellent radiation resistance, lower expansion coefficient, high strength and modulus of elasticity which make them extensively used in military equipments, balance weights for submarine and vehicles, aircraft components, nuclear and medical shields, kinetic energy penetrators, high temperature dies, etc...

CISRI-AT&M can produce various big sizes tungsten heavy alloy parts by CIP, various small parts by mold pressing, extruding or MIM, various high strength plates, bars and shafts by forging, rolling or hot extruding. Tungsten alloys with tungsten content ranging from 85 to 98% and a range of physical and mechanical properties as well as non-magnetic W-Ni-Cu can be offered, and also variety shapes, sizes and weights, ranging from several grams to over 500 kg, as well as blanks or finished tungsten parts can be offered.

Main Specification

Note: According to customer requirement, various size and shape machined products by different standards are available.


High Quality
We have inherited the tradition of strict demands on high quality products from Central Iron and Steel Research Institute (CISRI). In 2004, the company provided seven tons of tungsten heavy alloy shielding parts for the Alice detector of European Organization for Nuclear Research (CERN), including the largest tungsten alloy part with a weight of 1.3 tons. Owing to the excellent product quality and service, the Advanced Technology & Materials Co., Ltd (AT&M) was granted the Award for Best Industry of the Year 2004.

We are quite willing to provide any professional services, including product design, production, assembly and maintenance.
